Extreme Ultraviolet Astronomy

open access: yesAnnual Review of Astronomy and Astrophysics, 2000
▪ Abstract  Astronomical studies in the extreme ultraviolet (EUV) band of the spectrum were dismissed during the early years of space astronomy as impossible, primarily because of the mistaken view that radiation in this band would be absorbed by the interstellar medium.

An Ultraviolet Spectrophotometer for Satellite Astronomy [PDF]

open access: yesJapanese Journal of Applied Physics, 1964
An astronomical Spectrophotometer is described which was designed for use on OSOB, the second U.S. Orbiting Solar Observatory. The Spectrophotometer is intended to analyze the ultraviolet emission from stars and nebulae. The entrance slit of the Spectrophotometer defines the field at the primary focus of a 6-inch modified Gregorian reflecting ...

Discovery of 20 UV-emitting SNRs in M31 with UVIT

open access: yesThe Astronomical Journal, 2023
We present the first catalog of supernova remnants (SNRs) in M31 that exhibit diffuse ultraviolet (UV) emission. UV images of M31 were obtained by the Ultraviolet Imaging Telescope (UVIT) on the AstroSat satellite, and the list of SNRs was obtained from ...
